CS-CART PHP Shopping Cart 2.0

We sell Wholesale Towels and I have a Discount setup with UPS. In my online store, my products weight 100 pounds going up to 200 pounds and more.... Most of the time, my customer adds more than 3 or 6 cases or may be more. which is more than 150 pounds so for instance if my customer add 4 cases in their shopping cart each weight 120 pounds so 120 pounds x 4 = 480lbs total so what I want is 480 to be divided in to some kind of figure where I get the weight below 150 pounds from which I can easily ship the cases and off course once the system divided that 480 pounds into a number it would give me a correct shipping price for that certain pound I need to get weight below 150 pounds but allow my customers to add as many cases as they like, The weight must display on customer Invoice and on the checkout page, this shipping method must be in real time, and should work for all countries, and UPS shipping service. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
